At present, hex keys on the market are generally stamped and formed by a general-purpose punching machine. In the actual processing and production process, the processed hexagonal prism bars will be cut and then bent to process into universal hex keys.
[0003] When the existing hexagonal prism bars are processed into universal hex keys, they need to be cut into fixed lengths by a cutting die and then processed into universal hex keys by a bending device. When cutting, the hexagonal prism bars will be fixed in the cutting die, and the cutting mechanism of the cutting die will be driven by a hydraulic device to cut the fixed hexagonal prism bars, so as to cut them into the required lengths and then perform subsequent processing. However, after the hexagonal prism bars are fed into the cutting die, it is necessary to control the feeding device to adjust the cutting length of the hexagonal prism bars, and only the feeding end of the hexagonal prism bars is fixed during cutting, which easily leads to uneven cutting surfaces. Therefore, it needs to be improved. Content of the Utility Model

Detailed Embodiment
[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.
[0023] Such as Figures 1-4As shown in the figure, the utility model provides a technical solution: a cutting die with a limiting and elastic material feeding mechanism, which includes a base 1. One end of the top surface of the base 1 is fixedly installed with a mounting plate 2. A cutting component is arranged on the back surface of the mounting plate 2, a limiting component is arranged on the back surface of the mounting plate 2, a reset component is arranged on the top surface of the base 1, and an elastic material feeding component is arranged on the front surface of the mounting plate 2;
[0024] The cutting component includes a cutting plate 4, a cutting die core 5, a sliding groove 3 and a limiting column 6. The back surface of the mounting plate 2 is fixedly connected with the sliding groove 3. The cutting plate 4 is inserted and placed on the inner wall of the sliding groove 3. Cutting grooves and movable grooves are respectively formed through both ends of the back surface of the cutting plate 4. The inner wall of the cutting groove of the cutting plate 4 is fixedly connected with the cutting die core 5, and a material opening is formed through the back surface of the cutting die core 5. The limiting column 6 is fixedly installed on the back surface of the mounting plate 2, and the limiting column 6 passes through the movable groove of the cutting plate 4.
[0025] According to the overall structure of the device, the hexagonal prism bar is fed through the feeding device to pass through the feeding opening of the feeding die core 7 and the material opening of the cutting die core 5 respectively and then continue to be fed, so that one end of the hexagonal prism bar can abut against the elastic sheet 13. Since one end of the elastic sheet 13 is fixed and is limited by the limiting rod 12, when not offset, it will generate a certain force on the abutting hexagonal prism bar through elastic deformation, so that both ends of the hexagonal prism bar are fixed. Then, the cutting plate 4 is driven to press down by the hydraulic device, so that the cutting die core 5 and the feeding die core 7 are misaligned for cutting. After cutting, the material opening of the cutting die core 5 on the cutting plate 4 is aligned with the movable rod of the telescopic rod 15. At this time, the movable rod of the telescopic rod 15 will extend into the inner wall of the material opening of the cutting die core 5 through the spring two 14 because it is no longer blocked by the cutting plate 4, and the cut hexagonal prism is elastically ejected from the cutting die core 5 for blanking. After blanking, the movable rod of the telescopic rod 15 is driven to contract by the micro cylinder 16, and then the hydraulic device no longer presses the cutting plate 4, so that the cutting plate 4 is reset through the spring one 9.
[0026] As Figure 1 shown, a mounting groove is formed through the front surface of the mounting plate 2, and a feeding die core 7 is fixedly installed on the inner wall of the mounting groove. A feeding opening is formed through the front surface of the feeding die core 7.
[0027] By providing the feeding die core 7, the hexagonal prism bar can be fed from the feeding die core 7 to the cutting die core 5 through the feeding device.
[0028] As Figures 2-3 shown, the reset component includes a circular groove 8 and a spring one 9. The circular groove 8 is formed on the top surface of the base 1 and is located directly below the cutting plate 4. One end of the spring one 9 is fixedly connected to the bottom surface of the inner wall of the circular groove 8, and the other end of the spring one 9 abuts against the bottom surface of the cutting plate 4.
[0029] By providing the circular groove 8 and the spring one 9, when the hydraulic device no longer presses the cutting plate 4, the cutting plate 4 can be reset through the spring one 9.
[0030] As shown Figure 2 in the figure, the limiting component includes a limiting screw rod 10 and a limiting plate 11. Installation holes are provided through the sliding grooves 3 at both ends of the front surface of the mounting plate 2. The limiting screw rods 10 are respectively fixedly installed on the inner walls of the two installation holes of the mounting plate 2. Connecting holes are provided through both ends of the front surface of the limiting plate 11. The arc surface of the limiting screw rod 10 is fixedly connected to the limiting plate 11 through a fixing nut. A fixing component is provided on the arc surface of one of the limiting screw rods 10 and the front surface of the limiting plate 11. The fixing component includes a spring piece 13 and a limiting rod 12. A connecting hole is provided through one end of the front surface of the spring piece 13. The spring piece 13 is fixed to the arc surface of one of the limiting screw rods 10 through the connecting hole and one end of the fixing nut. The limiting rod 12 is fixedly installed in the middle of the front surface of the limiting plate 11. A limiting hole is provided through the middle of the front surface of the spring piece 13, and the limiting rod 12 passes through the limiting hole.
[0031] By providing the limiting screw rod 10, the limiting plate 11, the spring piece 13 and the limiting rod 12, one end of the hexagonal prism bar after feeding can abut against the spring piece 13. Since one end of the spring piece 13 is fixed and is limited by the limiting rod 12, when not offset, it will generate a certain force on the abutting hexagonal prism bar through elastic deformation, so that both ends of the hexagonal prism bar are fixed, and the cutting length can be adjusted by adjusting the positions of the limiting plate 11 and the spring piece 13 on the limiting screw rod 10.
[0032] As shown Figure 4 in the figure, the material ejecting component includes a telescopic rod 15 and a second spring 14. An installation groove is provided through the front surface of the mounting plate 2, and the telescopic rod 15 is fixedly installed on the inner wall of the installation groove. One end of the second spring 14 is fixedly installed on the inner wall of the outer cylinder of the telescopic rod 15, and the other end of the second spring 14 is fixedly connected to one end of the movable rod of the telescopic rod 15. A micro cylinder 16 is fixedly installed on the front surface of the mounting plate 2 through a bracket. The piston rod of the micro cylinder 16 passes through the outer cylinder of the telescopic rod 15 and is fixedly connected to one end of the movable rod of the telescopic rod 15.
[0033] By providing the telescopic rod 15, the second spring 14 and the micro cylinder 16, the material port of the cutting die core 5 on the cutting plate 4 after cutting is aligned with the movable rod of the telescopic rod 15. At this time, since the movable rod of the telescopic rod 15 is no longer blocked by the cutting plate 4, it will extend into the inner wall of the material port of the cutting die core 5 through the second spring 14, eject the cut hexagonal prism out of the cutting die core 5 for blanking, and after blanking, the micro cylinder 16 resets the movable rod of the telescopic rod 15.
[0034] Working principle: The hexagonal prism bars are fed through the feeding device to pass through the feeding port of the feeding die core 7 and the material port of the cutting die core 5 respectively, and then continue to be fed, so that one end of the hexagonal prism bar can abut against the elastic piece 13. Since one end of the elastic piece 13 is fixed and is limited by the limiting rod 12, a certain force will be generated on the abutting hexagonal prism bar through elastic deformation without deviation, so that both ends of the hexagonal prism bar are fixed. Then, the hydraulic device drives the cutting plate 4 to press down, so that the cutting die core 5 and the feeding die core 7 are misaligned for cutting. After cutting, the material port of the cutting die core 5 on the cutting plate 4 is aligned with the movable rod of the telescopic rod 15. At this time, since the movable rod of the telescopic rod 15 is no longer blocked by the cutting plate 4, it will extend into the inner wall of the material port of the cutting die core 5 through the second spring 14, and eject the cut hexagonal prism out of the cutting die core 5 for blanking. After blanking, the movable rod of the telescopic rod 15 is driven to contract by the micro cylinder 16, and then the hydraulic device no longer presses the cutting plate 4, so that the cutting plate 4 is reset through the first spring 9.
